Abstract

Embodiments of the present invention provide an access system and a communication method for an optical fiber network. A virtual ONU located on a user side is established, and an ONU control plane function, a PON MAC function, and a QoS function on an existing ONU is moved downwards to a virtual ONU. After the forgoing function modules are removed from the existing ONU, the existing ONU becomes an ONU physical converter and only has a function of converting the PON physical layer frame and the first user side physical layer frame.

Description

[0001] This application is a continuation of International Application No. PCT / CN2012 / 079767, filed on Aug. 7, 2012, which is hereby incorporated by reference in its entirety.TECHNICAL FIELD

[0002] The present invention relates to the field of communications and, in particular embodiments, to an access system, a communication method and a device for an optical fiber network.BACKGROUND

[0003] Because an optical fiber has a higher transmission speed and users have increasingly high requirements on bandwidth, it has become a development trend for an access network to replace a cable with the optical fiber. FTTH (Fiber To The Home) is a future development direction. However, direct fiber to the home requires re-laying out an optical fiber for each home, which has high costs. Therefore, FTTDp (Fiber To Drop / Distribution Point) is still used for a long time. A copper cable (such as a phone twisted pair cable, a cable TV cable, a power cable, or an Ethernet network cable) that has been connecte...
